A $55 pair of shoes was discounted 15 percent, making the sale price $46.75. The discounted price was then discounted again by 10 percent. Explain how you would find the final price of the shoes.
Answer:
$42.07
Step-by-step explanation:
If a pair of $55 shoes are discounted by 15%, then $55 (0.15) = 8.25. The pair of shoes were discounted by $8.25.
$55 - $8.25 = $46.75
If a $46.75 pair of shoes is further discounted by 10%, then $46.75 (0.10) = $4.675, or $4.68 rounded.
$46.75 - $4.68 = $42.07
Answer:
Sample response: The final price will be the discounted price multiplied by 100% — 10%. I could also multiply the discounted price by 0.10 and subtract that amount from the discounted price to get the final price.

MY 1st QUESTION, WILL GIVE BRAINILIST!
Scott's retirement party will cost $8 if he invites 4 guests. What is the maximum number of guests there can be if Scott can afford to spend a total of $14 on his retirement party? Solve using unit rates.
7, because 8/4 = 2 which means that 1 guest = $2. So if we do 14 / 2 to see how many guests that would be, it's 7.
Answer:
7
Step-by-step explanation:
Well if it's $8 for 4 people then you have to divide to get the rate:
$8/4 = [tex]\frac{2}{person}[/tex]
now you can divide the disired amount to get the number of people:
$14/ [tex]\frac{2}{person}[/tex] = 7 people

The expected attendance at a school event is 65 people. The actual attendance can vary by up to 30 people. Which equation can you use to find the minimum and maximum
attendances?
Answer:
|x-65|=30
Step-by-step explanation:
You are expecting 65 people, but usually 30 people come.
This equation works best since you can find both the minimum and maximum.
The equation can you use to find the minimum and maximum attendances will be |x - 65| = 30.
What is an absolute function?The absolute function is also known as the mode function. The value of the absolute function is always positive.
The absolute function is given as
f(x) = | x |
The expected attendance at a school event is 65 people. The actual attendance can vary by up to 30 people. Then the absolute function of the equation is given as,
|x - 65| = 30
The equation can you use to find the minimum and maximum attendances will be |x - 65| = 30.

Solve x-6y = 13 for y.
Answer:
y = 1/6x -13/6

x-6y = 13
Subtract x from each side
x-x-6y =-x+ 13
-6y = -x+13
Divide each side by -6
-6y/-6 = -x/-6 + 13/-6
y = 1/6x -13/6

Diana is buying plates and cups for a party. She wants the same number of each. Plates are sold in packs of eight and cups are sold in packs of 12. What is the least number of plates and cups she can buy? How many packs of plates? How many packs of cups? Explain how you know.
Answer:
What is the least number of plates and cups she can buy?
The least number of cups of plates and cups she can buy is 24
How many packs of plates?
3 packs of plates
How many packs of cups?
2 packs of cups
Step-by-step explanation:
What is the least number of plates and cups she can buy?
We solve this using the Lowest Common Multiple method
The L.C.M of 8 and 12
Multiples of 8: 8, 16, 24, 32, 40
Multiples of 12: 12, 24, 36, 48
Therefore,
LCM(8, 12) = 24
Hence, the least number of cups and plates she can buy is 24
How many packs of plates?
Plates are sold in packs of eight
Hence: 24 ÷ 8 = 3 packs of plates
How many packs of cups?
Cups are sold in packs of 12
Hence: 24 ÷ 12 = 2 packs of cups

Answer:
(-1, 7)
(0, 4)

(2, -2)
Step-by-step explanation:
y = -3x + 4
y = -3(-1) + 4 = 3 + 4 = 7
y = -3(0) + 4 = 4
y = -3(1) + 4 = 1
y = -3(2) + 4 = -6 + 4 = -2

You can use a scientific calculator
state whether the percent of change is a percent of increase or a percent of decrease. Then find the percent of change. original: 75, new:84
Answer:
The percentage of change is an increase of 12% from the original
Step-by-step explanation:
The percentage of change is a percentage of increase because the new value is greater than the original.
To find the percentage of change, we can divide the new value by the old which will give us the amount it increased by in decimal form, which we can simply multiply by 100 to find percentage:
84/75=1.12
1.12x100 = 112
The new value is 112% of the original, this means that the percentage of change is an increase of 12% from the original.
Hope this helped!
Answer:
increase and 12%
Step-by-step explanation:
84 -75 = 9
9 ÷ original # (75) = 0.12
0.12 x 100 = 12%
